That being said, if you are on one of the obsolete versions, such as Windows 7 or Windows 8.1, just know that these versions will reach end of service and no longer receive anything starting with January 2023. Big companies such as Google have also retired Chrome browser support for these old OS versions, so it makes more and more sense to upgrade. And, if you don’t want Windows 11 just yet, the obvious choice is good old Windows 10. And, speaking of this version, it just received a brand new cumulative update.

What should I know about KB5018482 for Windows 10?

The Redmond tech giant, aka Microsoft, has just released the optional KB5018482 Preview cumulative update for Windows 10 20H2, Windows 10 21H1, and Windows 10 21H2. This above-mentioned update includes nineteen bug fixes and enhancements, including a fix for graphics issues in Direct3D 9 games and a bug that caused OS upgrades to fail. Note that KB5018482 is part of Microsoft’s October 2022 monthly C update, allowing admins to test fixes coming in the November 2022 Patch Tuesday. Unlike the Patch Tuesday cumulative updates, the C preview-type patches are optional and do not include any security updates whatsoever. SPONSORED Remember that Windows 10 users can also manually download and install the KB5018482 preview update from the Microsoft Update Catalog. Let’s take a look at the changelog and see for ourselves what we should expect after downloading and installing it.

This occurs if the authentication level is below Packet Integrity. Addresses a DCOM issue that affects the Remote Procedure Call Service (rpcss.exe).

Before this cumulative update, Microsoft had not synchronized the blocklist to Windows 10 since 2019, effectively breaking this security feature. And, after installing this update, Windows 10 20H2 will be updated to build 19042.2193, Windows 10 21H1 will be updated to build 19043.2193, and Windows 10 21H2 will be updated to build 19044.2193.
